LOOM ELEMENT.

Specification of Letters Patent.

Patented Aug. 27, 1918.

Original application filed September 9, 1916, Serial No. 119.208.Divided and this application filed December 1, 1916. Serial No. 134,480.

To all whom it may concern Be it known that I, HOWARD I. Monnrs, acitizen of the United States, residing at San Diego, in the county ofSan Diego and State of California, have invented new and usefulImprovements in Loom Elements, of which the following is aspecification.

This invention relates to loom elements, and more particularly to theshed-forming means of looms, or the means whereby the warp threads orthread elements or groups of warp threads or thread elements arerelatively separated in alternately opposite re lations, to produce theshed formations which permit the introduction of the weft threads orthread elements or groups of weft threads or thread elements. Thepresent invention comprises one of the associated or combi.ed orinter-related features or elements disclosed in a prior application forS. Letters Patent, for looms, filed by me September 9, 1916, Serial No.119,208.

The invention has for its objects the provision of improved loomelements or an improved loom element, pertaining to shedforming means,which will be superior in point of relative simplicity and inexpensiveness in construction and formation, taken in connection with durability,positiveness and reliability in operation, and compactness in form,which will be generally superior in efiiciency and serviceability.

With the above and other objects in view, the invention consists in thenovel provision, formation and construction of parts and features, whichparts and features taken together constitute an improved shed-form ingmeans, element or finger, all as hereinafter described, shown in thedrawing and finally pointed out in claims.

in the drawing:

Figure 1 is a front elevation of an im proved shed forming fingerconstructed to constitute shed-forming means embodying the invention;

Fig. 2 is a side elevation thereof;

Fig. 3 is a top plan view thereof;

Fig. 4c is a view similar to Fig. 1 showing a pair of the shed-formingfingers in relat1ve positions to produce the shed, comprising a pair ofthe warp thread elements; and

Fig.6 is an isometric view showing a plurality of pairs of theshed-forming fingers arranged relatively to produce the shed including aplurality of warp thread elements.

In Figs. 2, 3, i and 5 warp thread elements are shown as associated withthe shed-forming finger or fingers, to illustrate the principle ofaction and mode of operation or method of use of the invention, and todisclose the working relation between the shedforming finger or fingersand the warp thread elements.

Corresponding parts and features in all the figures are designated bythe same ref erence characters.

Referring with particularity to the drawing, a designates warp threadelements, and Adesignates in each instance a thread-forming fingerformed and constructed to embody the invention, and each having anelongated body portion 6 carrying an outwardlyfacing rectangularlyrelated terminal portion 6, each of which latter is provided with astraight side edge 6 which is the leading edge with relation to thedirection of movement or progression of the finger if such finger orplurality thereof is mounted to move in or with relation to the path ofsupply or feed and final disposition of the warp thread elements; thenature of such mounting or the'means of so moving the fingers beingimmaterial in so far as the present invention is concerned. Each suchoutwardlyfacing rectangularly related terminal portion 6 is likewiseprovided with an up wardly inclined and rounded edge portion 6 arrangedoppositely to the straight edge portion 6, and which merges into suchstraight edge portion in a point 6 which constitutes specifically theend of the terminal portion 6*. The finger is likewise provided in theedge portion of the terminal portion 6* which is opposite to thestraight edge portion 6, and beneath the upwardly curved edge portion6", with a suitable warpthread receiving notch 6 such notch being thusformed in the following edge of the finger terminal portion 6 Theterminal portion 6 is disposed slightly forwardly of the vertical planeof the flat straight body 6, being connected therewith by a neck 6preferably rectangularly directed from said body portion 6; and theterminal portion 6 is preferably flat in formation and lies in a facialplane at right angles to the facial ihe operation, method of use andadvan tages, of the improved shed-forming means or finger for loomsconst1tutmg the invention, wlll be readily understood from the foregoingdescription, taken in connection with the accompanying drawing and thefollowing statement:

The shed-forming finger or a plurality of the same may be supported andmounted in any preferred and suitable manner, and may be actuated in anysuitable manner, so as to be properly applied to the warp threadelements a, to cause the relative separation of the same to produce theshed, or to produce a plurality of shed portions when. as usual, aplurality of such fingers are used, as illustrated in Fig. 5. Thefingers are reciprocated lengthwise, each finger being so rcciprocatedin a direction the opposite of that taken at any given phase ofreciprocation by the next adjacent finger, in producing a common form ofshed. Or, certain fingers may be grouped for joint reciprocation orreciprocation in a common simultaneous direction, or otherwisecontrolled and actuated, all within the predetermination and choice ofthe designer of the loom, and all in accordance with the pattern orweave of fabric to be produced by association of the weft threadelements with the warp thread elements. It is of course understood thatthe weft thread elements are applied to the warp thread elements, orassociated therewith, by a suitable shuttle element which operatesthrough the shed formation or formations in any desired or suitablemanner, As each finger is actuated toward and to the warp threads orthread units, as the latter are supplied in any suitable manner, thepoint 6 is projected between two adjacent threads or thread elements, ortwo series of threads or thread elements, producing a separation of suchthreads or thread elements or groups or series thereof, whereby itresults that the thread or thread elements or group or series thereofwhich is traversed or engaged or diverted by the rounded edge portion 6ultimately come into registration with the warp-thread receiving notch 6and the tension upon such thread or threads or thread or thread elementscauses the same to enter such notch 6 Thereupon, in a continuation ofthe same movement or actuation of the finger, the thread or threads orthread or thread elements is or are diverted from the normal plane ofthe warp threads, and one-half of a shed-formation is produced. As thedirecticn of actuation of movement of the in ger is reversed, this halfof the shed formation is caused to collapse and finally is succeeded bythe production of the opposite one-half of a shed-formation. lVhere twosuch fingers are jointly operated in opposite directions of actuation,it will be seen that complete shed formations will be produced as longas the threads or thread elements are in the respective notches 6 andthe weft threads are shot through such complete shed formation and thusassociated with the warp thread elements.

Any suitable means may be provided, such as that disclosed in theapplication initially hereinabove identified, for disengaging the warpthreads or elements from the fingers and the notches 6 therein, afterthe proper number of courses of weft thread elements have beenassociated with the warp thread elements with which the fingers havebeen engaged in single or successive shed-producing action. Thereupon,the shed-forming fingers may be successively associated with anddisengaged from other and further warp thread elements for theproduction of further shed formations inclusive of such further warptl'iread elenients. The teri'ninal portion 6 being oflset from thecommon plane of the body portion (5 and the neck 6, it results that thewarp threads or elements a are conveniently accommodated, in the notch 6at one side or adjacent to one face of the body portion 6 or the upperend thereof, or at one side of the neck 6 It is manifest that theshed-forming finger constituting the invention is extremely simple information and may be inexpensively formed or produced from a singleblank of suitable stock, and of exceeding inherent strength anddurability and well qualified for positive and eiiicient performance.

It is manifest that changes and variations and substitutions may be madewith respect to the particular construction, formation and organizationhereinabove described and shown in the drawing, without departing fromthe spirit of the invention or a fair interpretation thereof.

Havin thus disclosed my invention, I claim and desire to secure byLetters Patent:
